Comparison of three-dimensional reconstruction and CT-guided Hook-wire segmental resection for pulmonary nodules: a propensity score matching study

OBJECTIVE: To analyze and compare the clinical application value of three-dimensional reconstruction and computed tomography (CT)-guided Hook-wire localization for row lung segment resection of pulmonary nodules. METHODS: Retrospective analysis of the clinical data of 204 patients suffering from pulmonary nodules admitted to the Department of Thoracic Surgery of Gansu Provincial People’s Hospital from June 2016 to December 2022. According to the preoperative positioning method, the group was divided into a 3D reconstruction group (98 cases) and a Hook-wire group (106 cases), respectively. The two groups of patients were propensity score matching (PSM) to compare their perioperative outcomes. RESULTS: All patients in both groups underwent successful surgeries without perioperative deaths. After PSM, 79 patients were successfully matched in each group. Two cases of pneumothorax, three cases of hemothorax, and four cases of decoupling occurred in the Hook-wire group; no complications of pneumothorax, hemothorax, and decoupling occurred in the 3D reconstruction group. Compared to the Hook-wire group, the 3D reconstruction group has shorter operative time (P = 0.001), less intraoperative bleeding (P < 0.001), less total postoperative chest drainage (P = 0.003), shorter postoperative tube placement time (P = 0.001), shorter postoperative hospital stay (P = 0.026), and postoperative complications (P = 0.035). There was no statistically significant difference between the two groups in terms of pathological type, TNM staging, and number of lymph node dissection. CONCLUSION: Three-dimensional reconstruction and localization of pulmonary nodules enables safe and effective individualized thoracoscopic anatomical lung segment resection with a low complication rate, which has good clinical application value.
